Estimated shipping time

You can typically expect your items to arrive within 4–7 business days, depending on your location and product availability.

What is your Return Policy?

At Northgrid Supply, we want every customer to shop with confidence. If something doesn’t go as planned, we’ve made returns and refunds simple and fair. Here’s how it works:

1. Return Window

You can request a return within 30 days of receiving your order. Unfortunately, we’re unable to accept returns after that time frame.

2. Who Pays for Return Shipping?

  • If your item arrives damaged, defective, or incorrect, we’ll cover the return shipping cost.
  • If you’re returning an item because you changed your mind, you’ll be responsible for return shipping fees.

3. Damaged or Defective Items

Received something broken or not working properly? Contact us within 30 days. We’ll provide a prepaid return label and once the item is returned and inspected, we’ll issue either a full refund or a replacement—including any original shipping costs.

4. Changed Your Mind?

If you no longer want the item, you can return it within 30 days—as long as it's unused, in its original packaging, and in resellable condition. You’ll need to handle the return shipping, and once we receive and inspect it, we’ll refund the product cost (excluding shipping).

5. Refund Processing

Once we receive and approve your return, we’ll send a confirmation email and issue a refund to your original payment method within 7 business days. Please allow additional time for banks or credit card companies to process and reflect the refund.

If it’s been over 10 business days since your refund was approved and you still don’t see it, contact us at support@northgridsupply.com and we’ll look into it immediately.

6. Restocking Fees

In some cases, a restocking fee may apply depending on the item and return reason. If applicable, we’ll clearly communicate this during your return request process.

This 590-watt bifacial solar panel uses N-Type TOPCon cell technology to generate power from both the front and rear sides. Its bifacial design can produce up to 25% additional rear-side energy, depending on surface reflectivity.

Designed for residential, agricultural, commercial, RV, cabin, boat, grid-tie, and off-grid installations, the panel combines dual glass construction with a corrosion-resistant anodized aluminum frame. It is available in pallet quantities of 8, 10, 12, or 36 panels.

Key Features

  • Bifacial Power Generation: Generates energy from both sides and can provide up to 25% additional rear-side energy.
  • N-Type TOPCon Technology: Uses N-Type TOPCon solar cells with up to 25.1% cell efficiency.
  • Low Degradation: Rated at less than 1% first-year degradation and 0.4% annual degradation.
  • Low-Light Performance: Designed to maintain output during cloudy conditions and at dawn or dusk.
  • Incident-Angle Performance: Designed to maximize energy capture throughout the day.
  • Positive Power Tolerance: A 0 to +5W tolerance helps ensure at least the rated output.
  • PID Resistance: Advanced cell processing and module material control provide resistance to potential-induced degradation.
  • Harsh-Environment Construction: Designed to withstand salt, ammonia, sand, high temperatures, and high humidity.
  • Mechanical Load Resistance: Rated for a 5,400 Pa front load and a 2,400 Pa rear load.
  • Flexible Mounting: Pre-drilled holes support Z-brackets, tilt mounts, poles, ground mounts, and Nextracker mounting.
  • Pallet Shipping: Available exclusively in pallet quantities. Other quantities require direct sales assistance.
